WARP-THREAD-I-IOLDING DEVICE.

Application led April 17, 1912.

To all whom it may concern.'

Be it known that L'CHARLES D. LANNING, a Vcitizen of the United States, and a resident of Boston, county of Suffolk, and State of Massachusetts, (whose post-oiiice address is 95 Milk street, Boston, Mass.,) have invented an Improvement in Werp-Thread-I-Iolding Devices, of which the following description, in connection with the accon'ipanying drawings, is a specification, like characters on. the drawings representing like parts.

This invention relates to warp thread holding` means and more particularly to means for holding the threads of a warp in the `relation in which they come from the Slasher. The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is an elevation of a warp beam to the warp in which there is applied one form of my invention;

Fig. 2 is an end elevation partly in section of the warp and warp beam shown in Fig. 1;

Fig. 3 is a detail in front elevation of the warp holding device;

Fig. 4 is a sectional elevation taken on the line -i in Fig. 3;

Fig. 5 is a front elevation of a modiiied form; and

Fig. 6 is a section taken on the line (3*6 in Fig. 5.

In order to hold the ends of the warp threads in parallel arrangement and in the relation in which the Warp comes from the Slasher it has heretofore been a frequent practice to apply to the threads of the warp a flexible holding member such as a strip of adhesive tape. This is usuallv done while the warp is still in the slasher and before severance therefrom so that the threads being severed closely adjacent the tape are held in the same established relation which they occupied in the slasher. The beam can then be transported from place to place or the end of the warn handled or moved about for installation in a warp drawing-in, warp- Speccation of Letters Patent.

tying machine or other machine with assurance that the established relation of its thread ends will be maintained.

A flexible tape, however, while cheap, simple, economical and occupying a very small space has the disadvantage that it is not easy to grasp in the hands or is apt to tear if grasped in one or two places for the purpose of lifting or pulling the end of the warp. Furthermore, being flexible, it does not maintain the threads stretched but is apt Vto bend, iiex, buckle or double over so that the threads, while held on the tape itself in a parallel sheet, are not necessarily so held on either side of the tape where they may be crossed, due to the flexing of the tape. This renders uncertain any subsequent operation which depends upon the parallel relation of the threads, as for example, the application thereto of a clamp in a warp drawing niachine.

My invention contemplates the employment of thread holding means which is adapted to hold the threads in the form of a flat sheet and which is also capable of being easily grasped, whereby the end of the warp may be pulled about as when fastened by a clamp.

Preferably, though not necessarily, I employ a. flexible holding member such as a strip of adhesive tape with provision, however, for applying thereto relatively rigid stiening means. In the form shown in Figs. 8 and t, the holding member comprises a flexible member l which may be of paper or other suitable material fastened transversely across the warp threads 2, the latter being represented in Fig. l as wound upon the warp beam 3. lIhe flexible holding member 1, which may be prepared with one side gummed, is made in the form of a flattened tube, the gummed side being adhesively applied to the warp. When thus applied, as shown in Fig. l, it lies flat across the threads and resembles the holding tape of the prior art. To stiften the tape, however, there may be inserted in the tube at any time the longitudinal stifi'ening member 4 which herein is shown in the form of a rod having a pointed end 5 to facilitate its ready insertion in the tube, such rod extending preferably for substantially the entire length of the holding member. The rod may be of metal or wood, and may be of any desired cross sectional shape, but preferably it is more or less flattened so as to avoid undue thickness. When the rod is inserted the threads are held in a flat stretched sheet and may be pulled or drawn taut as in the case of a clamp, by seizing the holder at one or more points, the holder being readily grasped by the hands of the operator. This greatly facilitates the handling of the warp and renders more certain the parallel relation of the'threads.

The stiening member may be shorter than, or coeXtensive in length with, the flexible strip, but herein I have shown it as projecting beyond the ends of the latter, this making it possible to support the end of the Warp in a rack or the like for purposes of examining, manipulating or operating on the threads while thus held.

In Figs. 5 and 6, I have shown a modified form of the invention wherein a flat strip of ordinary adhesive tape 6 is employed, this being stuck transversely across the warp threads as usual. Depending from this tape, however, at suitable intervals, there are provided looped tabs 7 through the loops of which the stiflening member 8 is inserted, performing substantially the same function as the stiffening member 4 in Figs. 3 and 4.

Other means may be employed for carrying out some or all the purposes of this invention, but the foregoing embodiments will suffice to illustrate the principles thereof.

Claims:

1. The combination with a warp of a stiE- ened holder adhesively secured transversely the threads of the warp.

2. The combination with a warp of a holder adhesively secured transversely the threads to maintain them in parallel relation, and means for stiffening said holder.

3. The combination with a Warp of a thread holder, adhesively applied transversely the warp threads, and means thereon for receiving a rigid member.

4. The combination with a warp of a tubular thread holder adhesively applied transversely the threads, the tubular member being adapted to receive a rigid stiffening rod.

5. The combination with a warp of a thread holder applied thereto consisting of a gummed tubular paper strip.

6. The combination with a warp of a rigid member and means for adhesively securing the same transversely the warp threads.

7. A warp having a liexible holder adhesively attached transversely thereto, and means for receiving a stiifening member applied thereto.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
